Oh Henry!®

First introduced in 1920 by the Williamson Company of Chicago, many people mistakenly assume OH HENRY! was named after the famous ball player Hank Aaron, but the true origin of the name is much more amusing...

Way back when, there was a little candy shop owned by George Williamson. A young fellow by the name of Henry who visited this shop on a regular basis became friendly with the young girls working there. They were soon asking favors of him, clamoring Oh Henry, will you do this?, and Oh Henry, will you do that? So often did Mr. Williamson hear the girls beseeching poor young Henry for help, that when he needed a name for a new candy bar, he called it OH HENRY! and filed a trademark application the following year.
